A technique for register mapping in a virtual system includes preparing a register pool that includes a plurality of registers for mapping. A mapping table is prepared that has a register identifier (ID) and information related to each of a plurality of parameters that express an operational state of the virtual system for each of the registers. At the time a register access request is issued by a hardware thread, the register ID for an access target and information related to each of the plurality of parameters that express the operational state during operation is acquired. One of the registers, for which the acquired register ID and information related to each of the plurality of parameters match the register ID and information for each of the plurality of parameters within the mapping table, is set as a mapped register to be accessed per the register access request. |
